Boxplots reflect relative protein abundances quantified
from bulk and enriched tumor proteome data reported by
Bateman NW et al, 2024 - PMID: 38480868, further normalized
using a method described by Arike L et al, 2014 - PMID:
24791991. Protein abundances are categorized into tumor
purity tertiles predicted from companion whole-genome
sequencing data, i.e. low < 46% tumor purity; medium
46%-69.3%; high > 69.3%. P-values reflect MWU testing.
